Chapter 1885： Biodiesel and tractor **** dream

The excellent performance of the single-cylinder diesel engine has aroused great interest from Da Vinci and the students of the mechanical department. But this is not a good thing, and the adverse effect it brings is that the progress of steam engine research and development has stalled.

Because of the ultra-high speed of the diesel engine, the teachers and students of the mechanical department are extremely disgusted by the steam engine with a speed of only 50 rpm. After all, there is no harm without comparison. Then, most college students in the mechanical department went to study single-cylinder diesel engines. No one was interested in the steam engine for a while, so Marin was very depressed.

Marin also knows the superiority of the diesel engine, but the diesel supply is seriously insufficient! Before the development of science and technology to a certain level, especially the development of drilling technology to a certain level, the supply of diesel fuel cannot be sufficient.

Know that the oil fields of later generations are often hundreds of meters deep or even thousands of meters deep. The current technology, which can drill more than 100 meters deep, cannot supply enough diesel at all. Especially in some rock formations, there is no high-strength drill bit like that in later generations, and it is impossible to drill through.

So, what if we can manufacture a single-cylinder diesel engine? Without oil, the diesel engine is a pile of scrap iron ...

Different from steam engines, this thing burns coal. Marin, who controls the Ruhr and Newcastle coal fields, has the most indispensable coal. Moreover, the difficulty of obtaining coal is low all over the world.

Therefore, even if you know that the diesel engine is better, the steam engine is the easiest to promote. To this end, Marin had to adjust his strategy and began to stimulate Da Vinci and his students to develop steam engines.

Marin promised to make major research achievements in the steam engine, the reward is 10 times that of researching diesel engines. The specific standard is that the diesel engine research achievement award starts at 10 gold coins, while the steam engine research achievement award starts at 100 gold coins!

10 gold coins are less than one year's salary for ordinary people (12.16 gold coins), although there are many, but not too much. And 100 gold coins is equivalent to more than 8.2 times the annual salary of ordinary people. If an ordinary person is the basic salary of a monthly salary of 3,000, 12 gold coins are equivalent to 36,000. And 100 gold coins is almost equivalent to 300,000 soft sister coins ...

A periodic general research achievement will reward 300,000. This standard will be put into later generations, and those professors will also be tempted ...

And Marin promised-if anyone can get the steam engine on board successfully, or succeed in making a practical steam engine train, the reward is 1000 gold coins to start, and there is no cap ...

In other words, Marin's reward for steam engine ships and steam locomotives started at 3 million, which is very rich ...

For the diesel engine with higher technology content, Marin cut the reward by 10 times. The ordinary reward is only about 30,000 in the future. For the high-paying engineering and technical personnel, it is really not attractive ...

After being stimulated by this method, it turned out that most of the college students in the mechanical department went to study the steam engine. However, there are also a few pure-scholar college students who don't care about rewards. They are determined to continue to develop diesel engines. Marin was not disappointed. After all, one day, diesel opportunities will become mainstream. Right now most people study steam engines, and a few people study the proportion of diesel engines, which is exactly what Marin wants to see.

However, Marin was unwilling to use large-scale diesel engines for large-scale applications. Then, he suddenly thought of the very popular biodiesel technology in the 21st century.

The so-called biodiesel is a high-temperature esterification reaction of vegetable oils and alcohols (mainly methanol, or ethanol) in an alkaline environment to obtain biodiesel with a combustion performance very similar to diesel.

Biodiesel is environmentally friendly, contains no sulfur, and does not pollute the air. It is a key research direction in the 21st century. However, because the price of vegetable oil in later generations is more expensive and the cost is higher than that of ordinary diesel, it has been difficult to make a major breakthrough.

Marin remembered watching an agricultural program and introduced a plant called Jatropha curcas. The oil squeezed from its fruit can be easily processed into biodiesel, and the quality is quite good, which is better than domestic No. 0 diesel.

It is said that this Jatropha curcas is native to the tropical regions of southern North America, and the fruit is toxic, which can cause dizziness, vomiting, and diarrhea after consumption. However, the fruit has a high oil yield and is suitable for processing into biodiesel.

In fact, Jatropha curcas is the American version of tung tree. Its characteristics are very similar to tung tree. The fruit oil is a bit similar to tung tree oil.

Moreover, tung oil can actually be made into biodiesel. Marin's previous life has read reports that it seems to use tung oil and methanol for esterification reaction, and react for N hours in a strong alkali environment of potassium hydroxide ...

However, the Jatropha curcas was mainly introduced on the TV, but the Tung tree was not introduced. It can be seen that the Jatropha curcas certainly has the superiority as a source of biodiesel raw materials.

In fact, the processing of tung oil into biodiesel is not much worse than Jatropha curcas. But the problem is that oil tung trees have higher environmental requirements, and they only grow well in southern China.

Later generations of Lao Mei, South America, Paraguay and Argentina have introduced oil barrels, but as a result, the oil barrels did not grow well in the south of Lao Mei and the quality of tung oil produced was poor. In the environment of South America, the quality of tung oil produced in Paraguay is not bad, but it is not comparable to the tung oil produced in China.

The Jatropha curcas was promoted by television because of its strong adaptability. The TV program stated that Jatropha curcas does not have high requirements on the soil environment, is also very resistant to diseases and insect pests, and has a strong adaptability. I am afraid that this is the main reason why it has been vigorously promoted.

Anyway, Marin remembers that the oil squeezed from the fruit of Jatropha curcas will undergo an esterification reaction with methanol or ethanol under KOH and high temperature. As for the reaction for several hours, what is the ratio and how to remove the lye later, he does not know. After all, he is not a professional chemical worker.

However, knowing this, the following is easy to handle. Anyway, as long as there are enough raw materials, try a few more times, or even a few hundred times or thousands of times, you can always try out the ratio and reaction time, as well as the following purification methods.

Anyway, now Da Vinci has taught a group of chemical students. When there are more students in the chemical industry later, they will be divided into a group to study this, and they can always find a way.

According to the TV program of the previous life, the oil squeezed from the fruit of the jatropha curcas can produce 500 kg of biodiesel, which is half a ton.

If he planted his 10,000 acres of jatropha, the annual output of diesel would be 5000 tons! A 12-horsepower single-cylinder diesel engine consumes two or three liters of diesel per hour. Even if it does not stop, it will cost about 26,000 liters a year. The zero diesel has a density of 0.85 kg per liter. In other words, a 12-horsepower diesel engine runs at full power throughout the year, and only consumes about 22 tons of diesel. But in fact, the average single-cylinder diesel engine consumes three to five tons of diesel a year.

Calculated in this way, the biodiesel produced by 10,000 acres of Jatropha curcas can supply thousands of diesel engines for one year. If we increase the production of biodiesel by 100 times ...

Although in later generations, the cost of biodiesel is higher, it is not cost-effective. But for Marin in this era, whether or not it is the most important question. As for cost, it is secondary.

Even Marin came up with the exaggerated scene of using hand-held tractor formations to impact the enemy formation. Of course, first of all, he had to have a professional team of mechanics, put the single-cylinder diesel engine on the car, and make a rotten agricultural vehicle similar to the "four different" in later generations. Then, with the iron cover, you can use it as a turtle tank ...

Think of here ~ www.novelhall.com ~ Marlin's saliva will be left behind. Even the "Four Dissimilarities" for agricultural use in later generations, in this era, was enough to crush any enemy battles ...

However, after sobering up, Marin understood that he wanted to create a "chariot" like the "four different", and he first cultivated a qualified mechanical type. Da Vinci and the mechanical students under him, stayed in later generations, and even a mechanical apprentice was far behind. So, there is a long way to go ...

But if the "Four Dissimilarities" is researched, and the production of biodiesel is sufficient, it is estimated that the whole world will be shrouded in the shadow of the North Sea tractor and chariot. Thousands of tractors rushed towards you and asked if you were afraid?

……

Of course, that is just a bright future. First of all, to achieve that kind of bright future, Marin needs to send people to find the Jatropha first. Although it is known that in the north of North America, Kete is also very difficult to find.

Then, even if the Jatropha curcas tree is found, it will take several years to grow. Then squeeze out the oil of the fruit, and then use it to study the esterification reaction for the chemical students ... In short, it takes a long time, it is estimated that it will take decades, maybe Marin can't see it alive ...

But anyway, Jatropha has brought Marin a bright future for biodiesel and a better future for tractors to dominate the world. So, no matter how much it costs, Marin intends to find it ...
